Research On Multi-scheme Evaluation Method Of Indoor Central Air-conditioning Purification Project

The air quality in a building will directly affect the physical,mental and work efficiency of indoor workers.Taking the indoor air conditioning system of Sinopec Building as the research object,the effective control method of indoor air pollution in office buildings and its purification performance were discussed.Solve the problems in the original design,improve the air purification function of the air conditioning system in the building,and make the air quality of the building conform to the national excellent standard.The concepts of indoor air quality and air purification and the research status and development trend of domestic and foreign researchers in this field are described.The comprehensive evaluation method is used to evaluate and select the best indoor air quality and purification technology.The theoretical and mathematical models of evaluation and comprehensive evaluation are analyzed respectively.In view of the fact that the classification boundary is not clear,the fuzzy evaluation method is proposed to comprehensively evaluate the indoor air quality and air conditioning purification technology scheme.And the specific process of the evaluation is explained in detail through an example analysis.Several more suitable reconstruction schemes are put forward.Each reconstruction plan includes: the whole fresh air unit reconstruction plan,the single type air purifier plan,the fan coil unit purification reconstruction plan and so on.The comprehensive fuzzy analysis method is used to analyze the reconstruction scheme,and the evaluation index system is established.By means of experiment test and relevant data sorting and induction,the technical data that meets the project requirements and the comprehensive reconstruction scheme composed of each reconstruction scheme are obtained.Through calculation and analysis,the evaluation factor of the comprehensive reconstruction scheme is 0.912,which is superior to other reconstruction schemes.The purification function renovation project of central air conditioning system of Sinopec Building is used as an example to analyze.The research results and conclusions can be used as a reference for other office buildings to improve indoor environmental quality.
